The dedication of the Brazos County Arboretum acknowledges a gift to the Brazos County Master Gardener Association from Ms. Janis Atkins, founder of Brazos Natural Foods. The gift, given in memory of her parents Ira Lee and Mary Dewees, recognizes their life-long dedication to garden-ing and preservation of nature.

Ira Lee and Mary Dewees moved to Bryan, Texas upon Ira Lee’s retirement in 1980. One of the fi rst things they did was plant trees on their new property. In Baytown where they previously resid-ed they grew bay, camphor, oak and pecan trees. They brought seedlings of these trees with them and slowly added tree varieties adapted to this region, primarily oaks, that were readily available at the time. They then built their rose, perennial and vegetable gardens amongst them.

The Dewees were very generous in sharing the bounty of their gardens. Mary especially enjoyed passing along seeds, cuttings and divisions from their garden with her family, friends and neigh-bors as often as she could. The Dewees’ generous and curious nature passed onto their children and grandchildren who were fortunate to spend many moments in the gardens. Together they appreciated the seasonal experiences that nature provides.

The 24 trees that were planted are adapted to the growing conditions of the Brazos Valley and will provide a living, horticultural resource for its citizens to learn from and enjoy. The Arboretum and Demonstration Idea Garden encourages not only community beautifi cation, but also conserva-tion of natural resources. Trees reduce erosion, stabilize soils, provide habitat for wildlife, reduce noise pollution, provide shade and help home owners minimize water and energy use.

This project was made possible through the fi nancial and in-kind donations of Ms. Atkins, the Brazos County Commissioner’s Court, ISA-certifi ed arborists, the Brazos County Road and Bridge Department, Texas AgriLife Extension Agents, Extension Specialists and Brazos County Master Gardeners. Thank you for your contributions.

Brazos County Arboretum

Family TaxodiaceaeDescription This ancient tree is native to our region. It can live for centuries and

might grow 150 feet tall and spread as wide. Plant habit Large, deciduous conifer

Develops an elongated, pyramidal shapeLandscape use Plant as a specimen for a tall focal point or in a group for a robust yet

delicately-textured screen Locate carefully; provide ample space away from structures and utilities

Average mature size 70’ tall x 40’ wideGrowth rate Slow to fast, depending on water availability and soil fertility

Extremely long livedSun exposure SunSoil requirements Acidic to neutral; can become chlorotic in highly alkaline soilsWater requirements Thrives in waterlogged sites; develops root “knees” when planted near

water or in poorly-drained sites (beware if planted in a mown lawn)Tolerates dry conditions; drought tolerant once established

Heat tolerance High; adapts to urban conditions (refl ected street heat and polluted air)Foliage Deciduous, dark green needles; delicate, feathery texture

Yellow-bronze-brown fall colorFlowers Inconspicuous, brownishBlooming period SpringFruit characteristics Wrinkled, rounded conesPests and disease None serious; stressed plants may attract bagworms, spider mites, or

develop crown gall. Resistant to cotton root rot.Other Consider provenance (origin) of the tree; purchase a tree grown from a

regional seed source to ensure adaptability, as nursery stock of un-known origin may not survive (ask your nursery professional)Bald cypresses with a central Texas provenance generally out perform those from Louisiana swamps or the gulf coast which are less tolerant of alkaline soil.

BALD CYPRESSTaxodium distichum

(Taks-OH-de-um DIS-tik-um)Bald Cypress, River Cypress, White Cypress, Yellow Cypress, Red Cypress, Black Cypress,

Southern Cypress, Tidewater Cypress, Gulf Cypress, Sabino Tree

“The most useful of all coniferous trees for limey garden soils breaks with the traditions of its rela-tives by dropping its leaves in autumn… but never was shedding for a more worthy cause. The bald or river cypress turns by stages from its summer grey green, to a glowing fawn, and thence to a rich cinnamon and in its process provides one of the true spectacles of autumn.” - Scott Ogden, Gardening Success with Diffi cult Soils.

aphids; select a resistant variety Resistant to cotton root rotProviding good air circulation helps to prevent disease

Other Resist the urge to prune, as those left unpruned bloom sooner and heavier than those that are heavily pruned, an effect known as “crepe murder” or “crepicide.”

“[The crepe myrtle is] unrivaled among small fl owering trees in ease of culture, length of bloom period, interesting trunks and many other features.” - Neil Odenwald, Identifi cation, Selection, and Use of Southern Plants for Landscape Design.

“As a fast growing shade tree in Texas, Lacebark elm is tops.” - Dale Groom, Dale Groom’s Texas Gardening Guide.

“Botanists see no difference between the coast live oak and the escarpment live oak of the Hill Country, and in terms of how they look, they’re right. They’re both big, powerful looking live oaks. But there’s all the difference in the world in how they grow. The coastal live oak isn’t nearly as drought tolerant; around Houston, it lives in heavy clays, often in seasonally-standing water, and is usually draped with Spanish moss. One other difference; the coastal oaks aren’t as cold tolerant as its escarpment relative. All the live oaks growing between the Hill Country and the Gulf are hybrids of these two. - Sally Waskowski, Native Texas Plants.

“Scarcely any other tree develops the distinctive, spreading habit of the live oaks...” - Scott Ogden, Successful Gardening with Diffi cult Soils.
